Devyani is a consul, not a diplomat: she only represents her country when she's in her office, or traveling between offices, or working outside her office on job-related matters. The U.N. letter cites the U.N. Personnel Convention which explicitly states that any U.N. immunity she has is not to be used for her personal benefit, and furthermore India is supposed to waive it in these circumstances, rather than whisk her home.
It's very tough to get this message across to the Indian citizens about this. Most of the media cover for her. Many of my comments on Indian news sites, especially those with links to source material or criticizing the Indian diplomatic corps, are suppressed. Do you really think you're being well served by diplomats who support oppressing your fellow citizens and a media which blindly echoes their hollow claims?
